COMMERCIAL ASPECTS OF THE WORK 
issuance of this volume so many of them are 
but just coming into commercial sway, it is to 
the somewhat more distant future unquestion- 
ably that the greatest commercial triumphs are 
to be won for the world. And this is not be- 
cause the present-time creations are not splen- 
didly fulfilling their mission, but because the 
newer work has vastly greater possibilities. In 
the pitless plums and prunes, the new grasses, 
the thornless cactus, the new fast-growing 
forest trees, the frost-resisting trees, the work 
in new varieties of pears, apples, quinces, 
peaches, apricots and berries, together with 
other experiments under way which have not 
yet reached so advanced a stage, lie vaster 
commercial possibilities than in anything he 
has yet achieved, as well as a greater measure 
of service to the race.
